Method and apparatus for utilizing data collection and analysis function in wireless communication system

A method of adding a type of network-related analytic information provided by a network data analytics function (NWDAF) to the NWDAF, the method comprising:

• transmitting, to the NWDAF, an analytic information addition request requesting an addition of new network-related analytic information;
• and
• receiving, from the NWDAF, a response message including information about whether the new network-related analytic information has been added, in response to the analytic information addition request,
• wherein the network-related analytic information is obtained by analyzing information collected from at least one entity in a network, and
• wherein the analytic information addition request includes information about a definition of the new network-related analytic information.

A network data analytics function (NWDAF) comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to receive, by the NWDAF, an analytic information addition request requesting addition of new network-related analytic information, and transmit, from the NWDAF, a response message including information about whether the new network-related analytic information has been added to the NWDAF, in response to the analytic information addition request,
• wherein the network-related analytic information is obtained by analyzing information collected from at least one entity in a network, and
• wherein the analytic information addition request includes information about a definition of the new network-related analytic information.

A network function (NF) comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to transmit, to a network data analytics function (NWDAF), an analytic information addition request requesting addition of new network-related analytic information and receive, from the NWDAF, a response message including information about whether the new network-related analytic information has been added to the NWDAF, in response to the analytic information addition request,
• wherein the new network-related analytic information is obtained by analyzing information collected from at least one entity in a network, and
• wherein the analytic information addition request includes information about a definition of the new network-related analytic information.

A method of providing network-related analytic information available to a network data analytics function (NWDAF), the method comprising:

• receiving a provision request of a list of available network-related analytic information;
• and
• providing the list of available network-related analytic information in response to the request,
• wherein the available network-related analytic information is obtained by analyzing information collected from at least one network function (NF) and at least one application function (AF) in a network.
